Specifically, it can be divided into ordinary manganese-containing rails, copper-containing carbon steel rails, high-silicon copper-containing rails, copper rails, manganese rails and silicon rails.
Domestic rail brands mainly include U74, U7 1Mn, PD2, PD3 and BNbRE.
Among them, PD2 is the full-length quenched rail of plain carbon steel SQ process; PD3 is a high-carbon micro-vanadium low-alloy steel rail, and BNbRE is a low-alloy steel rail treated with niobium and rare earth.
Steel for railway is generally rare in other parts of Angang Group, and it is not easy to find!
